low price. very high power flash. beautiful white light. works with ttl

Cons:

no 45 degree angle (how rediculous is that?) - NOTHING between 0 and 60, extremely cheap build, oversize makes it easy to break, slow zoom (locks you out of taking photo while it zooms)

This flash works ok in ttl mode, lots of nice controls

very difficult to deal with lack of angles between straight forward and straight up - just a rediculous omission

the flash is a bit large and not as easy to manage

when the flash is busy zooming, it will not let you take a photo, good photos have been missed in the process

once i opened the pouch it came with and somehow the battery door had come loose on its own, not sure how to put it back without breaking it.

the first one i had, i had it in my front pocket and fell backwards. the flash fell out of my pocket when i hit the ground and would not work again, even though there was no cosmetic damage. (yeah i bought another because i needed a ttl flash and couldnt afford the oem, but now i think i might have to reconsider that notion)
